How to grow Tiarella in UK gardens
Light
Partial to full shade is best. Morning sun is fine; avoid harsh midday/afternoon sun to prevent leaf scorch. [rhs.org.uk]
Soil
Aim for moist, humus‑rich, free‑draining soil; add compost or leaf mould yearly. Protect crowns from excess winter wet on heavy soils. Water & feeding
Keep evenly moist during establishment and in dry spells. Feed lightly with a balanced, slow‑release fertiliser in early spring to keep growth tidy without making plants lush and floppy.
Planting
Plant in spring or autumn at the same depth as the plug, spacing 30–45 cm depending on variety and desired groundcover. Mulch to hold moisture and suppress weeds.
Maintenance
Deadhead spent flower spikes for a clean look; remove tired leaves after winter. Divide clumps every few years to maintain vigour and make free plants.
Pests & problems
Generally low‑trouble; watch for slugs/snails on young growth. Ensure drainage to avoid crown/root issues in winter.

FAQs
Is Tiarella fully hardy in the UK?
Yes—Tiarella is hardy in UK conditions and thrives in partial to full shade with cool, moist soils; just protect from excessive winter wet on heavy ground. [rhs.org.uk]
Will it spread?
Most garden cultivars are clump‑forming and slowly widen; some species run via short stolons. Divide every few years to refresh and increase stock.
Where does Tiarella look best?
Woodland borders, shady paths, under shrubs and in north‑facing beds; it also performs in containers with consistent moisture. Pair with hostas, brunnera and ferns.
What causes leaf scorch?
Too much direct sun or drought. Move to a shadier spot and improve moisture retention with organic mulch.
